The report, Collaborative Development: The Pros and Cons of P3s on Construction Projects (PDF), finds that public-private partnerships (P3s)- such as the proposed Illiana Expressway– offer the potential for significant cost savings for the public sector. P3s allow governments to increase internal investment, capitalize on the efficiencies and innovations of private companies, and build infrastructure slightly less expensively and slightly more quickly. For the private sector, P3s provide stable assets (infrastructure facilities) with predictable long-term returns from user fees for portfolio diversification. P3s also allow private entities, backed by the government, to borrow cheaply.
The Policy Brief utilizes case studies to demonstrate how P3s may be mutually beneficial and discusses the expected positive benefits of three potential P3 projects in the Midwest.
